I´ve just followed your link, DJ and this stood out to me:
EU nationals would be required to travel on a passport and not a national ID card. They would also have to apply for a biometric residence permit, which may include a fingerprint, after they had stayed for between three and six months.
There is nothing here that has not already applied to me at some point since I arrived in Spain. I needed a visa to come in, I applied for a 3 month Permanencia (permission to stay in the country), then another and another. Each time I had to surrender my passport for the duration, and have my fingerprints taken. After 3 Permanencias I could apply for a Residencia that was valid for 2 years, and yes, it had my photograph and my fingerprint on it. At the end of the 2 years I was given a Residencia for 5 years, again requiring a trip to the regional capital Police station for fingerprints. This 5 yearly trip was repeated until 2010 when the Residencia was discontinued for EU citizens (mot of whom have ID cards anyway), but continues for other nationalities.
In defiance of the EU’s free-movement directive, residence permits would not be granted to jobseekers. Instead, a specific “income threshold” would be introduced for “self-sufficient” migrants.
This already applies in Spain. If you are of working age and come to Spain without a job, and you want to register as a resident, you need to prove you have enough to live on and not be a burden on the State (an income more than the State's upper limit for those who qualify for some benefits), you must own a home or have a rental contract, and you also have to have a private health insurance that covers you for all eventualities, because State Health Care is Contribution based, not residence based.
